Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beefsteak and Smothered Onions
Ingredients
Directions
Fry slices of salt pork until very brown, then remove from the pan.
Add the steak to the pan and fry until done, then remove.
Add the sliced onions to the pan, cover, and cook slowly, turning occasionally until done.
Place the cooked onions on top of the steak.
Make a gravy by adding a little water, flour, butter, and coarse sea salt, then pour over the steak and onions.
